を特徴とするエンジンのオイル量減少讐告装置。A thermistor is fixed to the lowest safe oil level on an oil dipstick inserted into the engine's oil pan, and a constant current circuit is configured to flow a constant current through the thermistor, causing changes in potential due to changes in the resistance of the thermistor. It consists of a detection circuit, a control circuit that operates upon sensing a change in the potential and issues a signal to close the warning circuit, and a warning circuit that has a warning lamp or buzzer and closes the circuit in response to a signal from the control circuit. Features an engine oil amount reduction notification device.
